Some unusual results, including the existence of a bona fide solitary zero-eigenmode solution, are revealed for the Klein-Gordon equation. The cases of pure vector and scalar potentials, already analyzed in previous works, are obtained as particular cases.5141-5149engKlein-Gordon equationscreened Coulomb potentialvector-scalar potentialArtigo10.1142/S0217751X06025390WOS:000241911000005Acesso restrito
